Materials Testing Lab Offers Video Extensometer Technology

Smithers Rapra has announced the purchase of a video extensometer for its physical testing laboratory in Shawbury, UK. The noncontact video-based instrument, which can measure 3-D displacement and strain on materials, components and structures, is an alternative to traditional contacting extensometers. Many material tests are being replaced by these next-generation video extensometers, according to Smithers Rapra.

“Because of the increasing demands placed on the performance of polymeric materials and composites, we recognised the need to support our customers in this competitive market,” says Managing Director Mike Day. “Maintaining our highest service levels means we pursue long-term investments, ensuring our customers have access to the latest precision technology delivered with a fast turnaround.”

Noncontact extensometers enable productivity improvements compared with contacting methods, achieving ease of use with precision performance, according to the company. The technology is suited for batch testing, high temperature testing, use in harsh environments, high strain >100%, high-speed impact testing and the testing of very small (<1 mm) or delicate samples. Strain, shear strain, Poisson’s ratio, modulus, proof stress, ultimate stress and ultimate failure strain can be measured by the instrument.

Smithers Rapra provides global customers with a  range of independent contract services, consultancy and research on all aspects of plastics and rubber materials. It has extensive on-site analytical, testing and processing laboratories with relevant areas that work to CGMP guidelines.
